Genomic Characterization and Pathogenicity of BJEU06-1-Like PRRSV-1 ZD-1 Isolated in China

Figure 4

Rectal temperatures, average daily body weights, and PRRSV-specific antibody levels in the experimental piglets. (a) A rectal temperature ≥40.0°C was defined as fever. The mean ± SD (error bars) of temperatures is shown. (b) The body weight gain (kg) of piglets was calculated at 0, 7, 14, and 21 dpi. The mean ± SD (error bars) of body weight gain is shown. ^∗∗,  < 0.01; ns, no significant difference. (c) Pig serum was analyzed for PRRSV-specific antibodies. The threshold for seroconversion was set at a sample-to-positive (S/P) ratio of 0.4. The bars represent the average S/P of one group of piglets. The mean ± SD (error bars) of the specific antibodies is shown.
